Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
What are the current hot topics in type theory and static analysis?

Effect systems and Algebraic effects. ocaml has just released a stripped-down effect system. People are also working on Effect systems for Haskell (eff, fused-effects, effet). Koka is a language built with effects first and foremost and it’s rapidly gaining popularity. Unison also has effects.
[ANNOUNCE] GHC 9.6.1 is now available

There are also a few subtle issues that arise with delconts related to semantics of higher order effects (see here and here), but they might be solvable.

Looking for languages that combine algebraic effects with parallel execution

You'll get fearless parallel with STM in the mixture, and GHC is getting a work in progress effect system for Haskell, as Delimited continuation primops has been merged.
Should I pick up OCaml or Haskell?

My last example is algebraic effects, some of which have been made possible in a both practical and efficient way thanks to extremely recent research, and that I can use to implement architectures like Ports and Adapters or Clean Architecture and have very maintainable code. (Extensible Effects — An Alternative to Monad Transformers was published in 2013, Effect Handlers in Scope was published in 2014 and they are behind Polysemy, while there is ongoing work on effects with even better performance, like Eff)

cleff's Eff monad is esentially implemented as a ReaderT IO. [...] This is first done by eff, [...]

Here is link number 1 - Previous text "eff"3 projects | reddit.com/r/haskell | 1 Dec 2021
This is essentially how continuation based effect systems work, check out eveff and eff.
Where's more discussion of the designs of effect systems?
4 projects | reddit.com/r/ProgrammingLanguages | 17 Nov 2021
Languages such as Koka only support algebraic effects, not scoping operations such as catch and listen. The Effect Handlers in Scope paper introduces scoping operations, which lead to the Haskell libraries fused-effects and polysemy, but they turned out to have some weird semantics. eff is her effort to fix that.4 projects | reddit.com/r/ProgrammingLanguages | 17 Nov 2021
While her eff is still under construction, there are relative more mature pieces like Koka etc. I'd very much like to understand how her concerns map to those other effect systems, but can't find more write-ups about the design space of effect systems.
